Palladium on Barium Sulfate
Palladium on barium sulfate is a heterogeneous catalyst consisting of finely divided palladium metal supported on a barium sulfate carrier, typically containing about 5% palladium by weight. It is used in selective hydrogenation reactions, such as the reduction of alkynes to alkenes, in pharmaceutical and fine chemical synthesis. This product is classified under tariff item 2843.90.00 as an inorganic compound of a precious metal (palladium) that is not a colloidal precious metal and is not otherwise specified, and it does not meet the definition of a separate chemically defined compound.

More Specific Codes
This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the product is presented as a supported catalyst with a polymeric or other non-precious metal binder
Catalysts of a kind used for chemical reactions, with precious metal as the active substance, may fall in heading 38.15 if not classifiable as a compound of precious metals.
If the palladium is in colloidal form rather than as a supported catalyst
Colloidal precious metals are specifically classified in subheading 2843.10, while the supported catalyst is excluded from that subheading.
If the product is a mixture of palladium with other inorganic substances not meeting the definition of a compound
Chemical products and preparations of the chemical or allied industries not elsewhere specified may apply if the product is a preparation rather than a compound.

Import Tips & Compliance
• Ensure the product is properly described on the commercial invoice as 'palladium on barium sulfate catalyst' with the palladium content clearly stated, as this affects classification and duty calculation
• Verify whether the palladium content requires an import permit under Canada's Nuclear Safety and Control Act or other regulations, although catalysts of this type are generally not controlled
• Keep records of the chemical composition and intended use, as the CBSA may request them to confirm the classification under 2843.90.00
